If you would like to complete the square to form a true equation, you can do this using the following steps:

x^2 - 4 * x + ? = (x - ?)^2
x^2 - 4 * x + 4 = (x - 2)^2

The correct result is x^2 - 4 * x + 4 = (x - 2)^2.

-1/2u + 3/5= 1/6. What is u?

So to start off on answering we are going to subtract 3/5 from both of the sides:
−1/2u+3/5−3/5=1/6−3/5
−1/2u=−13/30
Okay, so now we are going to multiply both sides by 2/(-1):
(2/−1)*(−1/2u)=(2/−1)*(−13/30)
The final answer shall be:
u=13/15
I hope this helps!
